However, if it is desired to subject the board to forces at angles to each other, it is to be understood that the corrugations in the different reinforcing sheets may extend in different directions.

The composition board shown in Figure 3 consists of a single reinforcing sheet 10 embedded in plaster composition of any suitable type. As shown, one side of the reinforcing plaster 16 and the opposite side is covered with a layer of heat and sound insulating composition 14. As in the embodiment previously described, the reinforcing sheet 10 is formed with apertures 11, through which the composition on the opposite sides thereof are bound together. The finished surface of the board may be covered by fabric 17, or may be colored in any of the'manners described above. I

In use the composition board may be precast as wall sections, or panels in the conventional manner, theincreased strength due to the reinforcement enabling the sections to be made larger than has been customary heretofore. The panels or wall sections may be cast complete or may consist only of the reinforcement and the backing or insulating composition so that the finishing composition may be applied to the wall sections after installation. In certain typesof construction the latter is preferable since the wall may then be finished without dividing'the same into panels. As a further alternative the composition material may be built up from reinforcing sheets and plaster when a building is being constructed. I

By using a plurality of layers of plaster composition and reinforcing sheets as shown in Figures 1 and 2, the structure is adapted to serve as a supporting'wall as a substitute for bricks or studding. Since the reinforcing sheets may be pierced by nails or drilled in much the same manner as wood, the structure can be readily secured at any desired point. Furthermore, the use of moisture resistant reinforcing material prevents rapid softening and deterioration under the action of the weather. The interior finishing surface may be carried by the supporting'wall,

as shown, or may be constructed separately.

The structure shown in Figure 3 is adapted to serve as an interior wall covering in the manner in which ordinary wall board is used, and may be nailed directly to the studding in a frame building, or may be used in combination with a supporting wall constructed as described above.

Although the foregoing description is necessarily of a detailed character in order that the invention may be fully set forth, it is to be understood that modifications and re-arrangements of the parts may be resorted to without departing from the spirit and scope of the invention as defined in the following claims.

I claim:

1. A pro-cast wall section including a layer of plastic material, a layer of insulating material and a hard pressed fiber reinforcing sheet embedded therebetween.

2. A precast wall section including a layer of plastic composition, a layer of insulating material, and an apertured sheet of hard presser fiber disposed 'therebetween, said plaster and said insulating material being bound together through said apertures.

3. A wall including a plurality of'layers of plastic composition material, certain of said layers consisting of insulating material and other of said layers consisting of rigid material, and a plurality of reinforcing sheets separating adjacent layers and embedded therein.

4. A pre-cast wall section including a layer of plastic composition, a layer of insulating material, and an apertured sheet of hard pressed fiber disposed therebetween, the material formed to provide apertures through I which the insulating material and plastic composition may interlock. said plaster and said insulating material being bound together through said apertures.

5. A wall including a plurality of layers of plastic composition material, certain of said layers consisting of insulating material and other of said layers consisting of rigid material, and a plurality of reinforcing sheets formed to provide a plurality of apertures therethrough through which a material may extrude to interlock said sheets separating adjacent layers and embedded therein.

6. A wall including a plurality of layers of composition material, certain of said layers consisting of insulating material and other of said layers consisting of rigid material, a plurality of corrugated reinforcing sheets separating the adjacent layers the material of said sheets forming orderly rows of apertures to permit the layers of composition material to be embedded about said sheets.

7. A wall including a plurality of layers of composition material, certain of said layers consisting of" insulating material and other of said layers consisting of rigid ma terial,a plurality of corrugated-reinforcing sheets separatingthe adjacent layers the material of said sheets forming orderly rows of apertures to permit thelayers of composition material to be embedded about said sheets, the apertures in adjacent sheets being a in staggered relation to each other.

In testimony whereof I hereunto afiix my signature this 27th day of December, 1929.
